sPEcIFIcATIoN forming part of Letters Patent No. 741,545, dated Qctober 13, 1903 Application filed December 3.1902. 'SerialNo. 133,766. (No model.)

To aZZ whom, it may concern:

Be it known that I, NIELs PoULsoN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new anduseful Improvements in Metallic Finish'for Buildings, &c., of which the following is a specifi Figure 1 is'a horizontal section of sufilcient of a Window-frame having a swinging sash to illustrate my invention. fFigL 2 is a vertical section through the lower part of the sash and sill.

' The side frames A consist each of a strip of bent or drawn metal having three sides 2 3 4, the outer side 2 and inner side 3 being generally fiat and parallel and the sash side 4 being adapted to the sash-frame B. As shown, thesash-frame is intended to swing, and the side at is therefore curved inward to meet at one or more points the curved side 5 of 'the sash-frame, the curvatures corresponding to a circle having its center eccentric to that of the pivots G of the swinging frame to insure a quick opening. To form a substantial stop limiting the outward swing of the sash-frame, the latter is provided with a shoulder 6, which abuts against one side of a rib 7, formed by longitudinally bending the side 4 of the window-frame. To effectually seal the joint between the parts, one of the frames-for instance, the window-framehas its side bent inward, forming a recess 8 to receivea spring sealing-strip 9, consisting of a strip of flexi-' ble metal bent transversely to coincide with a volute, the coiled end of which lies against.

the side 5 of the sash-frame, while the flat end is secured by screws 10 to the windowframe. This strip is in yielding contact with the sash-frame and effectually excludes both wind-currents and water.

The window-frame is secured between the stone lintel D and the inside trim E by means of L-shaped brackets F, each of which is secured by a screw 12 to the lintel and by screws 13 to inwardly-projecting ears 14 of the window-frame. I

The outside moldings G and inside moldings H and retaining-strips I for the glass J each, like the window-frame A, consist of a three-sided drawn-metal strip solidified and strengthenedby a composition filling Z, of a material which isplastic orcan be made into a paste and which after itsintroduction Will become hard, its outer face thus constituting the back face or side of the composite strip. The solidified material must be capable of being readily perforated by screws, yet must be nonfriable-that is, it must not crumble when perforatedso as to solidly engage the screwthreads and hold the screws as they are held by the fibers of wood. I have found by exber of the adjacent sash or frame is a space y, in which is a sealing-strip 9.

It has been found extremely difficult to prevent the entrance of water between sills and the lower rails or members of a swinging sash. To obviate this difficulty, I make a longitudinal groove 22 in the sill and preferably a corresponding groove 23 in the lower face of the sash, although this may be omitted, and from the groove 22 I extend downward channels 24, open at their lower ends.

tended use that a material suitable for-this Thus if water enters below the sash it flows into the sill-groove and outward. A further protection is afforded :by an outwardly andinclined faces 1;, which will form tapering recesses with the other members and walls, which then I -fill with cement W.

It will be evident that features of invention herein described may be used in connection with doors and other finish forbuildings or furniture, 850.

I do not here claim the detailed features shown and described and constituting the subjcct of claims in my applications Serial Nos. 156,359 and 96,318.

Without limiting myself to the precise construction set forth, I claim 1. As an article of manufacture, a metallic finishing-strip for buildings, &c.,'consisting of a hollow metallic strip provided with solid non-friable composition adapted to receive and retain screws, substantially as set forth.

2. A strip constituting a substitute for woodwork consisting of metal bent to form closed and open sides, with a solid non-friable composition, the exposed face of which constitutes the other side of the strip and which is adapted to receive and retain screws, substantially as set forth.

3. A metallic framework, the members ofwhich are bent metal strips open at one side and filled with a solid pervious non -friable composition, substantially as set forth.

4. The combination in a metallic structure of members each consisting of a metallic strip bent to form an open-sided tube and containing a filler and secured to the structure with the open side against the structure, substantially as set forth.

5. The combination in a metallic structure of members each consisting of a metallic strip bent to form an open-sided tube and containing a filler and secured by screws to the structure with the open side against the structure, substantially as set forth.

6. The combination in a metallic structure of members each consisting of a metallic strip bent to form an open-sided tube and containing a filler of a pervious non-friable composition, and secured to the structure with the open side against the structure, substantially as set forth.

7. The combination in a metallic structure of a memberconsisting of a filled bent metallic strip open and inclined at one side and a filling of cement between the inclined side and the adjacent part of the structure, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
